How to help a very stressed fish settle in?
Hello! I just got a new fish from a friend but it appears the shipping process was a little much for the poor guy. He's floating on his side and just laying on the bottom gasping. I spent well over an hour adapting him to my quarantine tank's water (put him in a bucket with his old water and slowly combine tank water and the old water.) My quarantine tank is cycled and has no ammonia in it. While in his bucket, he was laying on the bottom. His color seems to have returned slightly, but not much at all. Is there anything I can do? I have some aquarium salt, MelaFix, PrimaFix, and some Ich Cure that I can add if need be (as in, it might help.) I have the lights off and the filter turned down for now. He's the only fish in the tank.
Anything I can do? He's not floating so I don't think he's devoloped swim badder due to stress yet. I don't expect him to make it, though, but any help would be appreciated.
